The serum-free suspension cell bank  Hela-F and the 293-F  have passed the verification review of the National Institutes for Food and Drug Control. We can screen for a variety of serum-free cultures for a cell to determine the most suitable serum-free medium for the cell, optimize the culture process, etc.
